I have a question as to how accurate are the Depth and Location reports =
coming from USGS. =20

As I understand it, USGS reports =E2=80=9C5 km=E2=80=9D as a depth which =
could be anywhere from the surface to 26,400 feet down.  I also wonder =
how accurate the epicenter is pinpointed.  Anyone know?
